Qur invention relates to devices for removing the end orends of cylindrical tulgiularmembers used as cores upon which kflexible sheets such as paper are wrapped.

'It' has been found particularly useful in eonnectionwitli'the vremoval of the damaged end or ends of the cores upon which newsprint, i. e., the paper used for the production Vof newspapers, is wrapped. n

' is well known, these rollsof paper are very heavy andthe ends ofthe heavy paper fiber tubular cores are provided with sheet metal ferrules which are used to form seats or bearingsfor stub axles forming that part of ,the printing press upon which the ypaper roll is 'mounted duringV the printing operation. n

These ferrules often become ,damaged or deformed during shipment of the rolls and must,Y vbe repaired or replaced 'before such rolls can benicunted in the press. In such Cases'the consignerv .or other agency resuensible for the damage is under obligation lto repair such damage before final acceptance yby the purchaser or consignee. Such repairs, inaddition to the cost of additional handling and transportation, also involves unrolling of the paper, provision of a new core, and rewinding of the sheet. This involves a considerable expense, as will be apparent. i

The iobject of our invention is to reduce such added expense to the responsible party by a simpliiication of the procedure in the repairs. Y vThis we accomplish by cutting off the end portions yof a damaged corel while the paper remains in place rolled up thereon and then substituting a temporary and reusable device which provides the required bearings or klseats for the stub axles previously referred to.

Our present invention therefore c-onsists of a device for removing the core ends and a method involving` such removal and the substitution of the reusable bearing members. i

The said invention consists of means and a method hereinafter fully described and particularly set forth inthe claims.

The annexed drawings and the follcwing description set forth ,indetalil certain means for carrying out our invention, the disclosed means, however, constituting but owne' of `the various mechanical. ferlfiii which the Prhciple of our-invention may be employed.`

In said annexed drawings:y F igure l represents a; fragmentary axial section of a newspaper,` nollf'showing a vdeformed core end, in this insta-nce bent into :elliptical form soas to preclude the practicability of straightening it soI` as to properly receive the stub axle.

Fig( 6" represents a section taken upon the4 plane kindicated .by yline VIVlf, Figg'.

Fig. 7 represents a section takenupon the piane indicated by une vii-vri, Eig. s.

Fig. 8 represents a detail in perspective showing the slide upon which the rotatable cutter is mounted. l

Fig. 9 represents a detail in perspective of the adjusting wedge forming ya part-of the device.l

F ig. Vl() represents a front elevation o f a complete4 roll partly in axial section and showing the substitute yand-reusable bushing member forming the seats foil the reception of the stub axles.

The cutting device illustrated includes a main or body portion l of general cylindrical form whose outer cylindrical surface 2 forms a bearing for the loosely mounted sleeve 3 whose outer surface 4l is frustoconical, the major diameter being at the outer end portion of the body member. The latter is provided with a circular plate 5 forming a flange of larger diameter than the interiorend diameter of the core and which is secured to the main partv of the lQody member by means of suitable screws such as cap-screws 6 6. However, this flange might be made integral with the main portion ot' the body member.

This latter is formed with a longitudinal slideway 7, the inner portion ot which is formed by a projection 8, Fig. 3. In this slidewa-y is seated an adjusting member 9, whose inner portion forms a wedge 10, the outer portion forming a threaded member 11 which passes through an aperture 12 iormed in the flange, and ot substantially the outer diameter of the threaded member. The latter also passes through a recess 13 ltermed in a handle 14 Which is secured in place by the said cap-screws (i-6, as shown in Fig. ,4.

The inner end ot' the main part of the body portion is formed with a` transverse dove-tailed slideway 1', Fig. G, in which is seated'a correspondingly formed slide 15, Fig. 8. This slide is provided at its outer end portion with al slot 16 and transverse apertures 17-17 which receive a journal pin 18 upon which is loosely mounted a rotatable circular cutter 19. The inner end ot the Vslide 15 is provided with a bearing boss 2O which rests upon the inclined surtace 21 of the Wedge 10. Ain adjusting nut 22 is mounted upon the threaded member l1 and bears against the handle 14 as f-:hown in Fig. B. v

This wedge member may be backed inwardly se as to permitthe device to be inserted in the interior of the damaged end portion 23 ot' the core 24, as shown in dotted lines in Fig. The outer minor vdiameter 4ot the sleeve 3 is made such that it may be jammed into this end portion until the tiange comes in'contac-t with the outer end oli' the sheet metal terrule 25 with one of which each ot the end portions o1 the core is ordinarily provided for reinforcement purposes.

The ,device having been so inserted into the core, the sleeve 3 acts as a bearing for the main body portion ot the cutter and the hitter may he manually rotated by means ot the handle; By now screwing up the nut 2.2, the wedge may be caused to engage the inner end otl the slide and cause the cutter to engage the inner portion ot the core.

The lei glh of' the core is made such that the cutter will reach inwardly beyond what expcricni-.fe may indicate is the maximum length o'lt the damaged end portion ot such core, as will be understood.

By continuingl the rotation and periodically screwing up the nut 22, it will be seen that this outer damaged end portion ot the core may be finally severed and removed as shown in Fig. leaving the main portion oit the core in place` rihe extension 8 acts as a hacking Yl'or the slide during the operation.

The other end ot the core. whether damaged or not, is removed in a similar manner.

A substitute device now inserted to take key (not shown) termed or secured on the corresponding stub axle and which prevents the latter li'roai turning in the terrule. This kc y structure is provided so that a brake may be applied to such stub axleand the braking action transmitted to the roll during printing, .is well known to those lskilled in the printing ait.

Vlfhe subst-itnte device includes two bushing members 27--27, each ot which is formed with an inner 'truste-conical end portion capable ot read insertion into the Core, an Youter triisto-coiiical end portion orsocket 2S) and an ititern'lediatc cylindrical portion 30. The portion Q9 forms. a shoulder Si adj accnt the cylindrical portion 30. The said portion QS) lurthermore is formed with the cvlind 4l recess or seat 32 which is adapted to receive the stub axle and ot the same size as the seat which was originally formed in the ierrule and is also formed with the key recess 33 corresponding with the recess of the ferrule.

The outer diameter ot the cylindrical portion is made such as to make a tight fit with the normal bore ot' the core.

rThe outer surface ot thel socket end portion nl the bushing is made truste-conical as shown, the major diameter being at the outer end. This major diameter is made such that this end frusto-conical surface will jam into the interior of the aperture in the paper roll formed by the removal ot' the severed part ot' the core.

llach ot these bushings is also formed with a longitudinal bore 34 through each ot which passes the reduced end portion 35 of a tension rod 3G. The outer ends o'l the latter are threaded as at Si' and receive the tightening nuts 38.

Atter the previously described severing operation has been completed and the severed coro end-jnntions removed, one of the bushing mcn'il'icrs is driven or pushed by handv into the interior of' the one end of the remaining part ot the core until the shoulder 31 engages the other end olf such core. The rod :lo :is then slipped into the core from the opposite end. inserted into the bore 34 olf the bushing member which is in place at the `other end and the nut 3S then screwed upon the projecting end ot the reduced end portion 35 ot said member. The other bushing member is then slipped upon the opposite end of the rod, jammed into the interior ot the core and its nut placed thereon. By screwing up one or both nuts, therefore, it will be seen that the two bushingl members will be drawn toward cach other and held in place by a coi'itinuonslv applied torce holding the bushlv termed with a recess QG which receives a lll?) mg membersV against the ends of the core,

i and the inner ends of the said members being),`

in contact with the shoulder 36 formed by the reduced end portion o the rod 36, the shoulders 3l being` in Contact with the ends oi the core. The roll is then ready for insertion in the press.

What we claim is:

1. In a device ot' the class described,

'the combination of a main rotatable member; a cutter mounted upon said main member and'mevable radially with respect thereto; means for adjusting,` said cutter axially with reference to Said main member; and a bearing` sleeve; said main 4member being formed with an exterior journal surface upon whichsaid sleeve is rotatably mounted.

2. The device described by `Claim l and in which the exterior surface of the bearing sleeve is truste-conical.

3.v rlhe device described by claim l and in which the cutter is mounted beyond the bearing sleeve and upon the innerend of said main member; and the outer end of the latter is provided with a flange' in Contact with said sleeve; -whereby said sleeve is located between said flange and inner end ofthe main member.
